PCI: Correct pci=resource_alignment parameter example

Browse Source 
The "pci=resource_alignment" parameter is described as requiring an order
(not a size) and the code in pci_specified_resource_alignment() expects an
order.

But the example wrongly shows a size.  Convert the example to an order.

Fixes: 8b078c6032 ("PCI: Update "pci=resource_alignment" documentation")
